I think this is where I disagree with you. Gardenhire was a part of those winning teams, sure, but there's a myriad of players you should also be thanking for winning divisions. Gardy himself didn't win divisions, just as Gardy himself didn't lose in the playoffs. Either the manager has something to do with the outcome of the game, or he doesn't. And if he doesn't, then anybody can manage a playoff team.
